Hydration FAQs
Is the "8 glasses a day" rule accurate?
The 8-glasses rule is a rough estimate. Actual needs vary by weight, activity level, climate, and individual factors. This calculator provides personalized recommendations.
Can I drink too much water?
Yes, water intoxication is rare but possible. It occurs when you drink extreme amounts quickly, diluting sodium levels. Stick to the recommended ranges for safe hydration.
Do other beverages count toward my daily intake?
Yes, but water is best. Coffee, tea, and milk contribute to hydration, but avoid sugary drinks. About 20-30% of hydration comes from food, especially fruits and vegetables.
What are signs of dehydration?
Dark urine, dry mouth, fatigue, dizziness, headaches, and reduced urine output. Severe dehydration requires medical attention.
Should I drink water even if I'm not thirsty?
Yes, thirst isn't always a reliable indicator. By the time you feel thirsty, you may already be mildly dehydrated. Drink regularly throughout the day.
